CRM 3 to 4 Upgrade. A "meta_5462ec7f342a4ac199923066b0b692ad" database was created RRS feed

  • Question

  • Hi all,

    I did a CRM 3 to 4 upgrade recently, during the upgrade the install failed up to the WorkflowUpgradeAction. I had review the implementation guide and found although the upgrade said failed, the CRM 4 should still work.

     

    However, after the upgrade I actually found in SQL Server there is a new database called meta_5462ec7f342a4ac199923066b0b692ad, had a lookup into the database itself looks like it definitely CRM related. Has anyone come across this before? Is it safe to delete this database?

     

    Thanks

  • Hi,

     

    I had never such a DB. It Is important that you hav all Workflow's stopped before you start the migration.

    Because of the complete new workflow engine the system could not all workflows migrate. so the most of the WF have you to reimplement under crm4. So I would advise to delete all complex workflows before starting the migration.

  • This 'meta_...' database will have been created for temporary use during the upgrade. I'm pretty sure it's afe to delete the database, but if CRM 4 is operational it'd be safer to take the database offline first and leave it offline for a while to check that it doesn't break anything, then delete it when you're happy

  • HI

    Is your crm system operational?

    Do you have _MSCRM and a _Config db in your db server?

  • Yes CRM works fine. And the _MSCRM and _config db are all there.

    Cheers

  • Maybe it was to do with the workflow. I redeployed CRM 3 and during upgrade I saw a warning saying workflow is running... but the actual workflow status was paused so I proceed with the upgrade....
